2. Note
Please read these operating instructions before unpacking and putting the unit
into operation. Follow the instructions precisely as described herein.
The instruction manuals on our website www.kobold.com are always for currently
manufactured version of our products. Due to technical changes, the instruction
manuals available online may not always correspond to the product version you
have purchased. If you need an instruction manual that corresponds to the
purchased product version, you can request it from us free of charge by email
([email protected]) in PDF format, specifying the relevant invoice number and
serial number. If you wish, the operating instructions can also be sent to you by
post in paper form against an applicable postage fee.
The devices are only to be used, maintained and serviced by persons familiar
with these operating instructions and in accordance with local regulations
applying to Health & Safety and prevention of accidents.
When used in machines, the measuring unit should be used only when the
machines fulfil the EC-machine guidelines.
3. Instrument Inspection
Instruments are inspected before shipping and sent out in perfect condition.
Should damage to a device be visible, we recommend a thorough inspection of
the delivery packaging. In case of damage, please inform your parcel service /
forwarding agent immediately, since they are responsible for damages during
transit.
Scope of delivery:
The standard delivery includes:
 Manual Pressure Measuring Devices with External and Integrated Pressure
Sensors model: HND-P231/HND-P233/HND-P236/HND-P239
4. Regulation Use
Any use of the Manual Pressure Measuring Devices with External and Integrated
Pressure Sensors, which exceeds the manufacturer’s specification may invalidate
its warranty. Therefore, any resulting damage is not the responsibility of the
manufacturer. The user assumes all risk for such usage.

5. Operating Principle
The highly precise KOBOLD hand-held pressure measuring devices HND-P231/-
P233/-P236 are measuring devices with integrated pressure sensors. They have
two pressure measurement inputs on the top of the housing, which are connected
to the measuring points by means of stable metal connections and plastic hoses
that are available as accessories. Numerous measuring ranges in the
overpressure and under pressure range are available for various measurement
tasks, such as differential pressure measurement. In addition to pressure display,
these first-rate, compact, universally applicable measuring units offer additional
functions such as minimum/maximum value memory, a hold function, tare
function, automatic self-shut-off, or zero point offset. The devices with an
expanded spectrum of functions also have a logger function, a peak value
memory, minimum/maximum alarm, an adjustable measuring cycle, and
averaging.
The KOBOLD hand-held pressure measuring devices HND-P239 have an
integrated pressure sensor for absolute pressure measurement. The measuring
device is connected to the measuring point by means of a stable, metal
connection on the top of the housing and an optional plastic hose. This device
design offers the possibility of also displaying the barometric air pressure in
relation to sea level »zero«. In this case, air pressure is corrected by entering the
height above »zero« in meters. Naturally, these devices also have the
minimum/maximum value memory, a hold function, a tare function, automatic
self-shut-off function, and zero point adjustment. The KOBOLD HND-P239
devices also offer additional functions like the logger function, peak value
memory, minimum/maximum alarm, an adjustable measuring cycle, and
averaging.
6. Electrical Connection
6.1 Mains Operation with Power Supply
Warning: When using a power supply please note that operating
voltage has to be 10.5 to 12 VDC. Do not apply overvoltage!! Cheap
12 V-power supplies often have excessive no-load voltage. We,
therefore, recommend using regulated voltage power supplies.
Trouble-free operation is guaranteed by our power supply HND-
Z002. Prior to connecting the power supply to the mains, make
sure that the operating voltage stated at the power supply is
identical to the mains voltage.

7. Operation
7.1 General
7.1.1 Safety Requirements
This device has been designed and tested in accordance with the safety
regulations for electronic devices. However, its trouble-free operation and
reliability cannot be guaranteed unless the standard safety measures and special
safety advises given in this manual will be adhered to when using the device.
1. Trouble-free operation and reliability of the device can only be guaranteed if
the device is not subjected to any other climatic conditions than those stated
under Technical Information.
If the device is transported from a cold to a warm environment condensation
may cause in a failure of the function. In such a case make sure the device
temperature has adjusted to the ambient temperature before trying a new
start-up.
If there is a risk whatsoever involved in running it, the device has to be
switched off immediately and to be marked accordingly to avoid re-starting.
Operator safety may be a risk if:
 there is visible damage to the device
 the device is not working as specified
 the device has been stored under unsuitable conditions for a longer
period of time.
In case of doubt, please return device to manufacturer for repair or
maintenance.
2. When connecting the device to other devices the connection has to be
designed most thoroughly as internal connections in third-party devices (e.g.
connection GND with protective earth) may lead to undesired voltage
potentials that can lead to malfunctions or destroying of the device and the
connected devices.
3. Do not use these products as safety or emergency stop devices or in any
other application where failure of the product could result in personal injury or
material damage. Failure to comply with these instructions could result in
death or serious injury and material damage.
Warning: If device is operated with a defective mains power
supply (e.g. short circuit from mains voltage to output voltage)
this may result in hazardous voltages at the device (e.g. at sensor
socket or interface).

7.2 Connections
Connection for pressure tubes:
„+“ = higher pressure, „-“ = lower pressure
Interface: Connection for el. isolated interface adapter
(p.r.t. chapter 8.5 Serial Interface)
The mains adapter socket is located at the left side of the device.
7.3 Display
7.4 Basic Operation
Please Note: Activating/deactivating tara clears the max- & min-
memories.

1) Zero-Point Adjustment: If there is no pressure or zero-pressure (absolute)
applied to the pressure ports the device will display 0. If there is a permanent
deviation (and device is operated under steady conditions), a permanent zero
point adjustment can be carried out. To carry out the adjustment press button 3
for approx. 5 seconds (Auto Null will be displayed shortly). The adjustment is
done via the OFFSET-value of the sensor (referring configuration menu).
To recall the manufacturer’s calibration press button 3 for approx. 15 seconds.
Please Note: A zero-point adjustment can only be carried out if
the difference between the value on display is less than 500
digits!
If a zero point adjustment was carried out the display shows
”Corr” after a restart .
7.5 Operation
After turning on, if the logger function is not off, the time of the integrated clock
will shortly be displayed. If a zero point adjustment was carried out the display
shows shortly „nuLL Corr“.
After changing the battery the clock-setting menu is activated automatically
(‚CLOC‘). Check the clock and adjust, if necessary (p.r.t. chapter 7.7).

7.6 Pop-up clip
Handling:
 Pull at label “open” in order to swing open the pop-up clip.
 Pull at label “open” again to swing open the pop-up clip further.
Function:
 The device with a closed pop-up clip can be plainly laid onto a table or
attached to a belt, etc.
 The device with pop-up clip at position 90° can be set up on a table, etc.
 The device with pop-up clip at position 180° can be suspended from a
screw or the magnetic holder.

7.7 Configuration
To change device settings, press Menu (key 4) for 2 seconds. This will call the
configuration menu (main display: „SEt“).
Pressing key Menu changes between the menues, pressing (key 3) jumps to
the refering parameters, which can be selected with key (key 3).
The parameters can be changed with  (key 2) or  (key 5).
Pressing Menu again jumps back to the main configuration menu and saves the
settings.
Quit (key 6) finishes the configuration and returns to standard measuring
operation.
